The story behind the name
Meet Theo.
Theo first made an impact as the name of the only son on "The Cosby Show," earlier it was associated with Vincent van Gogh's supportive brother Theo.
With Scottie, Bennie, Stevie, and Davey on the rise for girls, alongside Margo, Cleo, Juno, and Theodora, perhaps you may hear of more girls called Theo in the future.
